Notes from Table

Estimated Temperature Rise:

1. The rated current as listed is either the saturation current

or the heating current depending on which value is lower.

component with 30mm length 28 gauge buss wires and

applying the current to the device for 30 minutes. The tem-

perature is measured by placing the thermocouple between

the winding and the shield.

Trise = [Total loss (mW) / 6.288]^.833(^oC )

Total loss = Copper loss + Core loss (mW)

Copper loss = Irms²x DCR (Typical) (mW)

Irms = [IDC²+ ∆I²/12]^1/2(A)

Core loss = 6.81 x 10^-7x f (kHz)^1.1x (K x ∆I)^2.15(mW),

where f varies between 25 kHz and 300 kHZ, and B less

than 2000 Gauss.

2. The saturation current is the current which causes the

inductance to drop to 65ꢀ (or 75ꢀ) of its nominal induc-

tance at zero bias. This current is determined by placing

the component at room ambient (25°C), and applying a

short duration pulse current (to eliminate self-heating

effects) to the component.

4. In high volt*time applications, additional heating in the

component can occur due to core losses in the inductor

which may necessitate derating the current in order to limit

the temperature rise of the component. In order to deter-

mine the approximate total loss (or temperature rise) for a

given application, both copper losses and core losses

should be taken into account.

3. The heating current is the dc current, which causes the

temperature of the part to increase by not more than 40°C.

This current is determined by extending the terminals of the
